Figure 3: Example of Line Topology
NOTICE
Installing drives or power converters of different current ratings in line topology may result in unwanted power-off behavior.
l
Mount the drives or power converters with the longest discharge time first in the line topology. In normal operation, the
drives or power converters with bigger current ratings have a longer discharge time.

Star Topology
In a star network, all devices are connected to the same switch or switches. Star topology reduces the damage caused by a single cable
failure. In a star topology, a single cable failure affects a single device instead of all devices in the network. In many applications, this
topology enables simpler cabling depending on the location and distance of the device.
